Video games

Anime series


Sighborg Y is a humanoid-looking, green-colored robot with a blank, expressionless face. His body has an orange crescent screwed onto his back. His arms are tube-like, and his yellow hands are shaped like teardrops. A yellow gem resides in his white center. He has orange legs with pointy feet. Sighborg Y wears a name tag that says "Yamada" (Japanese: 山田).

His Soultimate, Belly Button Beam, turns people and other Yo-kai into other Kai-borgs.

He can fly with his crescent propeller on his back, but he is too heavy to lift off the ground.


Yo-kai Watch 3

Sighborg Y can randomly be found in stationary locations throughout towns in Springdale and BBQ. When spoken to by the player, a mysterious voice prompts the player to battle Sighborg Y. Upon defeating Sighborg Y, the announcer will inform the player if it was the real Sighborg Y. If it is, then the player will befriend him; however, if it is not, then it will be revealed to have been either Sighborg T, Sighborg W, or Sighborg S. They will bestow the player a random item.

Yo-kai Watch Busters 2

Sighborg Y can rarely be obtained as a Clu-T-fact memo in Yamada's Labyrinth.

"Android Yamada" is taken from the English word android, and the Japanese surname Yamada, which is commonly used as a placeholder name, similar to "Smith" in English.

"Sighborg Y" is a combination of "sigh" and "cyborg", with "Y". The Y likely stands for "Yamada".


Original Android Yamada

Sighborg Y's original design.

Sighborg Y is based on a design that was submitted for the second Yo-kai Contest in Japan.


  • Designed by Souta Fukushima, Sighborg Y is one of the two winning submissions for the second Yo-kai Contest held in 2015 in Japan. The other winning submission is Horizontail.
  • Sighborg Y's "random" nicknames are: Yamada, Yammy, Droidy, and Borg.
  • Interestingly, the narrator in his mini corners is the same person who provides his in-battle dialogue in the game.
  • When his medal is put inside the Yo-kai Blaster during a battle, the announcer won't say the tribe's name like with other Yo-kai. Instead, he says, ''It's Sighborg Y!''
  • There is a glitch where if a Yo-kai turns into Sighborg Y while charging up their Soultimate, it will look like Sighborg Y is doing a different Soultimate.
